The transducer is the part of the spirometer through which the patient blows; it measures the air flow.
Sibelmed is the only manufacturer with 3 different transducers: Disposable Lilly, Fleisch and Turbine
Disposable Lilly Transducer with filter
The Lilly disposable transducer with filter is accurate and reliable.Its disposable system prevents cross-contamination between patients and its ergonomic design is very comfortable for pediatric tests. Currently, it is the most used option in Primary Care.
Due to Covid-19, the ERS/SEPAR societies indicate that spirometries must be carried out using a viral/bacterial filter to avoid any risk of contagion between the patient and the technician.
Based on these recommendations, we have developed an innovative solution that integrates a disposable transducer and filter in a single piece, reducing the risk of contagion between patient and technician by more than 99.99%.
Its new design, together with a controlled manufacturing process, means that the transducer does not need to be pre-calibrated.
This innovative Class IIa solution according to regulation 93/42/CEE:
- Protects technician and patient.
- It is economical, as it is a single consumable.
- Saves time, since when discarded it does not require disinfection.
- It is the only 2 in 1 solution on the market.
- It is hygienic, with individual packaging.
- It is comfortable, because the transducer and filter are integrated in the same piece.
- It is suitable for adults and pediatrics.
New disposable lilly transducer with integrated filter, for safer, more comfortable and faster spirometry.
Fleisch Transducer
The SIBELMED Fleisch transducer features an accurate pressure sensor.
It is used in a numerous pulmonary units.
It requires an antibacterial filter to ensure there is no transmission between patients.
Turbine transducer
Measuring transducer through a helix. This is the most affordable model.
It requires an antibacterial filter to ensure there is no transmission between patients.
